Letters Patent No. 100,344, dated March 1, 1870.

The Schedule referred to in these Letters Patent and. making part of the same.

To all 'whom it may concern:

Be it known that I, G. WATERS, ot the cit-yof Cincinnati, county of Hamilton, and State of Ohio, have Vinvented a new and usel'ul lrnprovemnt in Feed- Water Heaters and luritiers for Steam-Boilers, and for the purpose ot'ienabling others skilled in the art to make my invention, I append the following description ofthe saine, which l hereby declare to be t'ull and accurate, reference being had to the accompanying drawings which make a partof these specitications, with lettersof reference marked thereon, in vwhich drawingv Figure 1 represents a plan of the purifier, having the top removed, and

Figure 2 isat-ransverse vertical section taken through the feed-pipe H, v

A in the drawings represents a. portion of. the shell of the boiler' t0 which the heater is to be attached B is the external shell or main body of the purifier, of', say, thirty inches diameter, by thirty-sixincbes high.

C is another cylinder, say o'f from two to four inches less diameter than B, and not-quite so high, and open at top, with the upper end turned over-as shown.

1) is another cylinder' similar tothe-'last in construcf tion. and oi' less diameter', and about halt the height ot C; and e E, still Aanother' cylinder, in all respects similar'` to the last in construction, and ot' about twelve inches diameter, and twelve inches high. .v

All these concentric cylinders are attached lto a common bottom, and the whole atlixcd iu a'suitable manner in a vertical position upon or over a boiler.

H is the water-supply pipe to the apparatus.

Fand G are blow-ott pipes perforated and arranged between the chambers U 1), and D E.

1 is a hole communicating between the bottom of apparatus and boiler.

This apparatus may be made, round or square, of cast-iron or boiler-iron, or other .suitable metal, but preferably of cylindrical form, and ot' boiler-iron t'or the external shell or casing B, while-.the interior concentric cylinders (l D E, ot' which vthere may be any .desirable aandoen-may be of thinner sheet-iron.` `.lhe.

outer shell only has to withstand the steam pressure ofthe boiler to which it is attached.

The object of the apparatus is to purify the feedwater to steam-boilers by subjecting the same'to the action ofthe heat ot'the steam while passing up through the annular space between B and O, and so ou, as can be readily-seeuand comprehended by reference to the drawings, Atill it reaches the boiler through I.

In passing over the. top of the cylinder C, and into the next compartment, the water-'will be subjected on all sides in a very thin sheet to the action'ot' the steam,

and in like manner as it passes over D and E.

In constructing the apparatus in' this cylindrical form, I am enabled -to have exposed avery large' sur 'v tace ot' water constantly' to the action of the steam, v

and at the same time within a very small compass, and it is probably theonlytbrrn and arrangement practically adapted to locomotive purposes. Limeand tlie'rarious salts contained in water being subjected to such a heat of stt am, will be split up into their elements, and then of their' own gravity, aided b v t-he pressure otstearu downward, will be precipitated to thelbottom, whence they can b'e blown oli'at pleasure through pipes F G provided for the'purpose.

ln this description I have supposed the hole I to be of such size as to'enable thewater to pass t'reely to the boiler, and ha'if'e large communications or free passage ot' steafo from boiler.` It' desirable., however, there may be two pipes or passages,onc tor steam and one for water; or the steam may be admitted at top.

The pipe that passes the water to boiler may terminate below the waterline itthoughtlbest. n Haring thus suliciently described my invention, l claim and desre'to have secured to me by Letters Iatcnt'ot'the United States- The concentric cylinders l5 O D E, when constructed and arranged substantially as described and for purposes sctforth.

In testimony whereof I have hereunto set vrn y band this day ot' 1869.
